* mmc: Allow 2 byte requests in 4-bit mode for tmio_mmcYusuke Goda2010-10-291-5/+12
| | | | | | | | | | | | | Adjust the tmio_mmc block size check to accept 2-byte requests in 4-bit mode if the hardware supports it. Tested with the SDHI hardware block included in sh7724.

* mmc: Allow the tmio_mmc mfd driver to specify get_cd handlerArnd Hannemann2010-10-291-0/+13
| | | | | | | | | | Some controllers, supported by the tmio_mmc driver do not have the card detect pin of a slot connected, so that polling needs to be used and card detection is handled by other means. This patch exposes a get_cd hook for that purpose. Signed-off-by: Arnd Hannemann <arnd@arndnet.de> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* mmc: fix the use of kunmap_atomic() in tmio_mmc.hGuennadi Liakhovetski2010-09-101-3/+4
| | | | | | | | | | | | | | | | | kunmap_atomic() takes the cookie, returned by the kmap_atomic() as its argument and not the page address, used as an argument to kmap_atomic(). This patch fixes the compile error: In file included from drivers/mmc/host/tmio_mmc.c:37: drivers/mmc/host/tmio_mmc.h: In function 'tmio_mmc_kunmap_atomic': drivers/mmc/host/tmio_mmc.h:192: error: negative width in bit-field '<anonymous>' Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Acked-by: Eric Miao <eric.y.miao@gmail.com> Tested-by: Magnus Damm <damm@opensource.se> Cc: <stable@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* mmc: remove the "state" argument to mmc_suspend_host()Matt Fleming2010-05-271-1/+1
| | | | | | | | | | | | | | | | | | Even though many mmc host drivers pass a pm_message_t argument to mmc_suspend_host() that argument isn't used the by MMC core. As host drivers are converted to dev_pm_ops they'll have to construct pm_message_t's (as they won't be passed by the PM subsystem any more) just to appease the mmc suspend interface. We might as well just delete the unused paramter.

* tmio: add a platform flag to disable card write-protection detectionGuennadi Liakhovetski2010-05-221-1/+4
| | | | | | | | | | Write-protection status is not always available, e.g., micro-SD cards do not have a write-protection switch at all. This patch adds a flag to let platforms force tmio_mmc to consider the card writable.

| | | | | | | | | | SDHI controllers on SuperH, served by the tmio_mmc driver, can use slave DMA for data transfer. This patch adds support for the dmaengine API to the tmio_mmc driver.

* tmio_mmc: Use 100ms mmc_detect_change() delayMagnus Damm2010-03-071-1/+1
| | | | | | | | | | | | | | | This patch changes the tmio_mmc driver to wait 100ms before checking the card detect status. This type of delay is quite common among mmc drivers, it seems that most hardware platforms need to give the hardware some time to settle before checking card availabilty. Hotplug is half-broken without this patch on the sh7724 Ecovec board. Hot insertion seems ok but eject is never detected without this patch.

* mfd: tmio_mmc hardware abstraction for CNF areaIan Molton2010-01-181-40/+19
| | | | | | | | | | | | This patch abstracts out the CNF area code from tmio_mmc which is not present in all hardware that can use this driver. This is required so that we can support non-toshiba based hardware.

* tmio_mmc: fix clock setupIan Molton2009-06-131-10/+5
| | | | | | | | | | | | | | | | | | | | This patch fixes the clock setup in tmio_mmc. * Incorrect divider setting * Cruft written to the clock registers (seemingly harmless but Not Good (tm)) It also eliminates some unnecessary ifs and tidies the loop syntax. Thanks to Philipp Zabel who discovered the divider issue, commenting "Except for the SDCLK = HCLK (divider bypassed) case, the clock setting resulted in double the requested frequency. The smallest possible frequency (f_max/512) is configured with a divider setting 0x80, not 0x40." Signed-off-by: Ian Molton <ian@mnementh.co.uk> Signed-off-by: Pierre Ossman <pierre@ossman.eu>
